This invocation to Patañjali is said to be written by Raja Bhojadeva in 1100 AD, author of Rajamartanda Vrtti a commentary on the Yoga Sutras. It is chanted at the beginning of a yoga class. The first part of the chant salutes Patañjali's achievements as a founding figure in yoga; in grammar; and in ayurvedic medicine. The second part salutes him for carrying the conch, which symbolizes the vibrations of the Universe and also awakens us to the victory over the world of matter; the wheel, which symbolizes the dominion and universal power of wisdom; and the double-edged sword, symbolizes discriminative understanding, which enables us to see the duality and cut through it to reveal reality. The reference to ‘1,000 heads’ is to his form as Ananta or Adisesa, the divine serpent that, in biting its own tail, symbolizes endlessness or the circle of eternity from which all possibilities and universes can spring.
